I've got a problem with keychain on Leopard, and it seems related someway to Cyberduck.
When I open my keychain and I select any ftp entry I got this error:

Error: invalid parameter not satisfying: aString != nil

No problem with any other entry.

The strange (for me) thing is that if I edit manually the keychain entry adding an ftp address in the empty field that in Italian is called something like "Located" (the 4th field, after "Account"), the problem is solved, I can now select the entry without errors, but Cyberduck won't recognize that entry and asks me for a password.
Obviously after I enter the password it creates a new keychain entry like the old one, with the same problems.

I use CD 2.8.1 (3290) and Leopard with the new update.
